' WILLIAM F. OLAIP, OF ALLEMANGE, NORTH CAROLINA.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 225,109, dated March 2, 1880.

Application filed October 23, 1879.

To all whom it may concern Be it known that I, WILLIAM F. ULAPP, of Allemance, in the county of Guilford and State of North Carolina, have invented a new and Improved Refrigerator, of which the following is a specification.

The object of my invention is to furnish a simple and efficient apparatus for cooling liquids and freezing ice-cream by means of chemicals.

The invention consists of an oscillating or rotary vessel provided with compartments for the coolin g-inixture and the liquids to be cooled and a central chamber for the reception of the ice or other refrigerant and the vessel containin g the cream, the several parts being arranged. and operated in the manner fully described farther on.

In the accompanying drawings, Figure 1 is a vertical cross-section of my improved refrigerator, taken on line at w of Fig. 2; and Fig. 2 is a horizontal section of the same, taken on line y y of Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the base of the refrigerator, provided with circular openings a for the reception of cups, glasses, and other vessels, which are placed in said openings while being filled from the faucets.

B is a cylindrical outside vessel, having under its bottom I) rollers c, which rest on the top (I of base A. At the exact center of bottom bis a pivot, c, which is passed through top 01 and secured by a nut, f. VesselB turns freely on pivot c, and the rollers c steady its movements. I

Inside of vessel B is another vessel, 0, of less diameter than B, so that a space, 9, is left between the two vessels. Vessel O is provided with a bottom, h, some distance above bottom b, whereby a space, 6, is left between the two bottoms, h b, which communicate with each other through openings '5.

at the top by an annular plate, 70, extending from the top edge of vessel B to the walls of vessel D, as shown in Fig. 1.

Within vessel D is placed the ice-cream vessel J, which is of such a size that a space, I, is left between it and vessel D for the reception of ice or a chemical freezing-mixture, as may be desired.

To the under side of bottom m of vessel J is fixed, at the center, a socket-piece, a, which receives the pivot 0 on the bottom It. Vessel J is provided with a close-fitting cover, 19, to the center whereof is fixed a pivot, 19.

K is a cap, which fits over vessel J and over the top of vessel D. The lower end of said cap rests on the annular plate 7c. Pivot p is passed up through the top of cap K, and its projecting end is provided with a crank-wheel, g, by means whereof the vessel J is rotated or oscillated on the axis formed by pivots 0 p for the purpose of properly agitating the cream to facilitate its freezing, &c.

L is a faucet for drawing off the liquid contained in vessel B, and M M M M arefaucets leading respectively from compartments F G H I. Vessel B is provided with a filling-orifice', 4", made in plate It, and is provided with a funnel, N. Similar orifices are made for each of the compartments F G H I.

The manner of using the refrigerator is as follows: For a mixture to produce the cold I use either one of the following compounds: first, two parts of copperas and one part of Sal-soda; second, two parts of saltpeter and one part of sal-soda; third, one part sal-ammoniac, two parts saltpeter, and three parts of bicarbonate of soda. One of these compounds is placed in the vessel B and the proper quantity of water added. The four compartments F G H I are now filled respectively with wine, milk, lemonade, and coffee, or any other liquids that it may be desired to cool. When thus prepared the vessel B is oscillated and rotated for the purpose of agitating the mixture and causing the elements to combine, and thereby absorb the latent heat of the liquids. in compartments F G H I, and thus lower their temperature.

When ice-cream is to be made the cream is placed in vessel J, and in vessel D is placed one of the freezing-mixtures above described. This freezing-mixture is agitated by rotating and oscillating vessel B, and at the same time the cream is agitated by rotating and oscillating vessel J by means of crank-wheel q.

Instead of a freezing-mixture such as above described, ice and salt may be placed in vessel D around ice-cream vessel J, for the purpose of freezing the cream.

If it is not desired to use the apparatus for making ice-cream, the vessel J may be taken out and the vessel D used for the reception of a mixture to assist in cooling the contents of vessel 0, thereby exposing the contents of said vessel to cold on both sides; and when icecream is being frozen the freezing material in vessel D aids that in vessel B to cool the contents of vessel 0.

Having thus described my invention, I claim W. F. GLAPP.
